As speaker Lisa Sardinia, a Pacific University biologist, describes it:
"If the genome is the keyboard of a piano, then the epigenome is the fingers playing those keys. Epigenetic changes are involved in differentiation during development, a well-orchestrated pathway. Recently, it has become clear that the environment can alter these epigenetic modifications and, more surprisingly, these modifications can sometimes be inherited. In this presentation, I’ll introduce the mechanism of epigenetic modification, as well as newly discovered environmental effects on epigenetic modifications."
PS: This is one of HGP's weekly open-to-the-public Sunday-morning meetings. People generally begin to gather at the Friendly House by 9:40, and while street parking within a couple of blocks is almost always available, you may want to arrive early.
